, AUTOMATIC LINER SAFETY.

Application filed. January The present invention relates to an attachable safety locking device for use in linotypes or similar type-casting machines 'to protect mold liners; this device fastens to the under side of the intermediate channel having a locking and unlocking device which moves into and out of the entrance of the intermediate channel automatically. It is supported or held in posit-ion by attachable brackets and positively overcomes the damaging of mold liners by ejector blade while cams are rotating.

To the above and other ends, Which will be found as the description proceeds, this invention resides in the arrangements of a combination of new parts throughout and in the details of its construction, hereinafter described and claimed.

The form of this invention is illustrated in the accompanying drawing, in which Fig. 1 is an interior view of the invention; Fig. 2 is a perspective view of a model of the invention connected with the under side of the intermediate channel R.

Referring in details to the drawing, the present invention is a preferred embodiment of steel parts, having as its essentials:

A frame 8 (Fig. 1), containing a longitudinal channel extending from bracket 15" to hood screw 10, through which transfer blades 2 and textend. Transfer blade 2 is constructed in a sort of angular form having two fingers A and B; finger B is forced upward when finger A is released by lug 16, there being a coil spring 1 connected with a hood base screw 17 and finger A. The upward movement-of said finger B brings it 1nto engagement with lug (l of a channel latch 3, raising it at F, there being an interposing coil spring in wall of said channel latch 3 at E it is held in elevated position closing said channels entrance.

lVhen the vise mechanism of said typecasting machines is opened for making changes of molds or liners its trimming knife block or sector cover H is withdrawn from a sectional justification lever 5 at G leaving said justification lever free from pressure and hanging to its hinge l4 and lugs 13 and 16.

The said channel latch 8 having been raised in the entrance of said intermediate 19, 1926. Serial No. 82,282.

channel it thereby prevent-s the line of matrices'from going into the first elevator head unless it is withdrawn when the dial lever I is properly adjusted. This obstruction being offered at S Fig.2.

There is a long finger and delivery slide mechanism having a lower end starting roller which engages a starting clutch, located on the main cams of said type-casting machines. The said cams are caused to rotate when said starting clutch is engaged by said starting roller which may contain a line of matrices at its opposite end or long linger Q.

The unlocking arrangement contains a dial lever key 6 which is slotted at 9 making it adjustable, an interchangeable trans fer blade 4 adapting it for use on various models. Its front end is slotted at K accommodating a channel latch screw 7 which enables said channel latch to be drawn clownward by said dial lever key 6 which is also operatively connected with said dial lever I which controls and changes the size of ejector blades, its lug D being engaged by dial lever key 6 when registering multiple 4 at I (Fig. 2). l i The frames inside wall P, N and L aligns with inner wall J of said channel latch 3 adapting itfor attachment to the under side of said intermediate channel.

This invention constitutes a positive and practical mold liner safety arrangement, automatic throughout. It operates by raising the ejector scale lever to size 4: and back to the size of blade wanted. this should be done before the operator sends in his first line of matrices for each length or size of slug used.

Having thus described the invention I claim V In an I automatic liner safety device, adapted to be attached tothe lower side of the intermediate channel, a channel latch located at the entrance of the intermediate channel and movable into and out of the path of the leading delivery slide finger, an interchangeable ejector dial lever key adapted to engage a lug on an interchangeable transfer blade connected with the channel latch, an interchangeable justification lever movable into and out of the path of the trimming knife sector cover or block adapted to withdraw an outside transfer blade,
